because they don't share a side.
B. Yes, ADEF and AGHI can be proven
congruent by HL.
C. No, there isn't enough information
because the triangles aren't right
triangles.
D. Yes, ADEF and AGHI can be proven
congruent by SSS.

A. No, ADEF, and AGHI aren't congruent because they don't share a side.

hope it helps...

have a great day!!

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
